Milk and water are in the ratio of 3:2 in a mixture of 80 litres. How ...
Quantity of milk = (80 x 3/5) = 48 liters
Quantity of water in it = 80 - 48 = 32 liters
New ratio = 2 : 3
Let quantity of water to be added further be x litres
Quantity of water in it = 80 - 48 = 32 liters
New ratio = 2 : 3
Let quantity of water to be added further be x litres

Milk and water are in the ratio of 3:2 in a mixture of 80 litres. How ...
Given information:
- Ratio of milk to water in a mixture = 3:2
- Total mixture = 80 litres
To find:
- Amount of water to be added to make the ratio of milk to water equal to 2:3
Solution:
Let's assume that the amount of milk in the mixture is 3x and the amount of water is 2x.
According to the given ratio,
- 3x + 2x = 80
- 5x = 80
- x = 16
So, the amount of milk in the mixture = 3x = 3 × 16 = 48 litres
And the amount of water in the mixture = 2x = 2 × 16 = 32 litres
Now, we need to add some water to the mixture to make the ratio of milk to water equal to 2:3.
Let's assume that we need to add y litres of water.
After adding y litres of water, the total amount of water in the mixture will be 32 + y litres.
And the total amount of milk in the mixture will remain the same, i.e., 48 litres.
So, the new ratio of milk to water will be:
- Milk: 48
- Water: 32 + y
This ratio should be equal to 2:3.
Therefore,
- Milk/Water = 2/3
- 48/(32+y) = 2/3
- 144 = 2(32+y)
- 144 = 64 + 2y
- 2y = 80
- y = 40
Therefore, we need to add 40 litres of water to the mixture to make the ratio of milk to water equal to 2:3.
Hence, the correct answer is option B, i.e., 40 litres.
- Ratio of milk to water in a mixture = 3:2
- Total mixture = 80 litres
To find:
- Amount of water to be added to make the ratio of milk to water equal to 2:3
Solution:
Let's assume that the amount of milk in the mixture is 3x and the amount of water is 2x.
According to the given ratio,
- 3x + 2x = 80
- 5x = 80
- x = 16
So, the amount of milk in the mixture = 3x = 3 × 16 = 48 litres
And the amount of water in the mixture = 2x = 2 × 16 = 32 litres
Now, we need to add some water to the mixture to make the ratio of milk to water equal to 2:3.
Let's assume that we need to add y litres of water.
After adding y litres of water, the total amount of water in the mixture will be 32 + y litres.
And the total amount of milk in the mixture will remain the same, i.e., 48 litres.
So, the new ratio of milk to water will be:
- Milk: 48
- Water: 32 + y
This ratio should be equal to 2:3.
Therefore,
- Milk/Water = 2/3
- 48/(32+y) = 2/3
- 144 = 2(32+y)
- 144 = 64 + 2y
- 2y = 80
- y = 40
Therefore, we need to add 40 litres of water to the mixture to make the ratio of milk to water equal to 2:3.
Hence, the correct answer is option B, i.e., 40 litres.
